<@U04UQ68083H> where to change configuration in ory hydra database

In Ory Hydra, you can change the configuration related to the database in the configuration file. This file can be loaded using the `-c path/to/config.yaml` or `--config path/to/config.yaml` flag. For example, if you want to use a PostgreSQL database, you can specify the DSN (Data Source Name) in the configuration file like this:  ```yaml dsn: <postgres://hydra:[email> protected]:5432/hydra?sslmode=disable&amp;max_conns=20&amp;max_idle_conns=4   ```  You can also specify the issuer URL in the configuration file:  ```yaml urls:    self:     issuer: <https://oauth2.example.com>   ```  After changing the configuration, you need to apply the migrations using the `hydra migrate sql` command:  ```bash /opt/hydra/bin/hydra -c /opt/hydra/config/hydra.yml migrate sql -y <postgres://hydra:[email> protected]:5432/hydra?sslmode=disable   ```  Please note that the SQL adapter supports PostgreSQL 9.6+, MySQL 5.7+ and SQLite. Older MySQL versions may have issues with Ory Hydra's database schema.  For more details, you can refer to the [Ory Hydra documentation](<https://www.ory.sh/docs/hydra/self-hosted/deploy-hydra-example#install-ory-hydra>).
